Correct bolt selection is critical to achieving secure and leak-free joints, particularly in high-pressure or high-temperature installations. Choosing the appropriate property class (such as 8.8 or 10.9) ensures that the bolts can safely sustain the forces generated by tightening and system pressure without yielding or failure.
In fluid handling applications, properly torqued bolts maintain gasket compression and prevent leaks in flanged connections. Under-tightening can lead to fluid loss or contamination, while over-tightening may damage threads or compromise seal integrity. Proof load data helps engineers apply the correct tightening force with confidence.
Material strength, temperature, and corrosion resistance must also be considered. For hygienic or corrosive environments, stainless steel or coated bolts provide durability and ease of maintenance while meeting food industry standards. Using verified proof load data ensures mechanical reliability and extends the lifespan of critical joints.
This table serves as a practical reference for maintenance teams and design engineers selecting fasteners for pumps, valves, and pipework. Accurate use of bolt proof load information helps prevent joint failures, maintain system safety, and optimize performance in demanding fluid handling operations.
